An informal seminar series to highlight work from early career researchers from institutions around the world.
This week our speaker is Anthony Taylor. Many of you know Anthony from his days as a graduate student at UW-Madison! Anthony is now a postdoctoral fellow at UT Austin. On Monday, Anthony will be telling us about his ongoing search for broadline AGN. Please see the title, abstract, and Zoom connection details for the seminar below. You can either join us in person in the 4th floor conference room or through the zoom link provided below. Hope to see you there!
Title: Ongoing Searches for Broadline AGN in JWST Deep Fields with NIRSpec MSA and NIRCam WFSS
Abstract: Since the launch of JWST in late 2021, our ability to detect broadline emission from Active Galactic Nuclei (AGN) has been greatly enhanced at higher redshifts (4<z<7). At these redshifts, the easily detectable H-alpha line lies in the near- to mid-infrared at 3-5 microns. As such, the NIRSpec MSA multi-object spectrograph and the NIRCam imager in its Wide Field Slitless Spectroscopy mode are ideal instruments to detect high-redshift broadline AGN. In this talk, I will discuss recent results of my ongoing search for broadline AGN in the CEERS and PRIMER-UDS deep fields. I will describe my methods for data reduction, broadline identification, and line fitting, as well as preliminary conclusions regarding the population of identified AGN and their implications for galaxy evolution during and after the epoch of reionization.
